[Persistence of paradoxical sleep in the cat after destruction of the pontine gagantocellular tegmental field with kainic acid].

The pontine gigantocellular tegmental field (FTG) does not play any role in paradoxical sleep (PS) since the destruction of the cell bodies of the FTG with kaïnic acid does not alter PS in the Cat. Elimination of PS following electrolytic destruction of the ventrolateral pontine reticular formation can be explained by lesions of fibers connecting the region of the locus caeruleus and the bulbar reticular formation.
